Abstract

Functionalized triarylphosphines are obtained with good yields in a one-step reaction of an equimolar mixture of chlorodiphenylphosphine and an aromatic bromide in NMP or DMF at 110° C in the presence of zinc dust and a catalytic amount of NiBr2 (bpy). A possible catalytic pathway is discussed.
